Abstract

This invention provides a fixing structure of a PCB of an electronic product including PCB, a control panel and a pair of fixing plates, among which, a space for assembling the PCB is set inside of the back of the control panel, the flexible fixing plates are set at both sides of mutual opposite surfaces of the space to support the edge of the PCB. The result of this invention is that a PCB can be fixed by multiple fixing plates formed on the control panel, which can reduce numbers of fixing parts necessary for fixing the PCB and reduce the production cost.

Description

technical field [0001] The present invention relates to electronic products, in particular to a printed circuit board fixing structure for electronic products. Background technique [0002] A printed circuit board (PCB, printed circuit board) having various line terminals is used in electronic products, and the printed circuit board is mounted on a control portion of the electronic product. For the convenience of description, a microwave oven in an electronic product is taken as an example to illustrate the printed circuit board fixing structure. [0003] figure 1 It is a three-dimensional view of the appearance of a general microwave oven. [0004] As shown in the figure, an oven door 3 is provided on the front side of the body 1 of the microwave oven. The oven door 3 is for selectively opening and closing the cooking chamber (not shown) inside the body 1, and one end thereof is a central axis. The other end is rotatable forward and backward, and a door handle 5 is provi...
